Creating triggers to populates some audit table or say populating data in audit columns (created_by, updated_by,created_date,updated_date) is fine i believe, however this use case was to load/persist data in table with SCD-2 style, so is it good idea to use the trigger for such use case? Not sure of the exact pros and cons, but we were following certain rules like , if it's business logic which needs to be implemented in Database, then it should not be done using triggers but rather should be done through database procedure/functions. Hope this understanding correct. Regards Sud
